Guide To CNC Chuck Jaws: Soft Jaws vs. Hard Jaws
soft jaws are more adaptable but wear out faster, while hard jaws are more durable but less flexible for customizing the fit of the workpiece. ...

A scroll chuck is a type of lathe chuck commonly used in machining to hold and rotate a workpiece securely while it is being shaped, drilled, or cut on a lathe. It's called a scroll chuck because it uses a spiral-shaped scroll plate inside the chuck to simultaneously move all of its jaws in or out when the operator turns a key.
Scroll chucks are most commonly found as 3-jaw or 4-jaw configurations, but the 3-jaw self-centering scroll chuck is the most widely used in machine shops.
Inside the chuck body, there is a spiral scroll plate with grooves.
3-Jaw Self-Centering Scroll Chuck (most common)
4-Jaw Self-Centering Scroll Chuck
| Feature | Scroll Chuck | Independent Jaw Chuck |
|---|---|---|
| Jaw Movement | All jaws move together | Each jaw moves separately |
| Centering | Self-centering | Manual centering required |
| Speed | Faster to set up | Slower setup |
| Accuracy | Less accurate | High precision possible |
| Best For | Round or hex stock | Irregular shapes & precision work |
